-# Ideally lcdexec should be re-written so that menu definitions
-# look somewhat like:
-#
-#[Menu]
-#Type=Menu
-#Entry=SubMenu1
-#Entry=SubMenu2
-#
-#[SubMenu1]
-#Type=Action
-#Exec=/bin/program to execute with parameters
-#
-#[SubMenu2]
-#Type=Action
-#Exec=/bin/otherprogram with parameters
-#
 # Further Extensions:
+# - shell selectable in command sections
+# - type definitions instead implicit depending on Exec/Entry
+#   (the latter only as fallback)
 # - use input for parameters e.g. IP-Adresses, Sliders
-# - display result if a command on Screen
+#   e.g. Exec="ifconfig ${IF} ${IP} netmask ${MASK} broadcast ${BCAST}"
+#   where
+#   - ${IF} is the result of a selection input screen
+#   - ${IP}, ${MASK}n ${BCAST} are the results of IP input screens
+# - display result if a command on the display
 # - jump to other menus depending on the output/result of a command
